Formula feed for female minks during maintenance period and preparation method of formula feed

Abstract

The invention discloses a formula feed for female minks during the maintenance period and a preparation method of the formula feed. The feed comprises the following components in parts by weight: 30-40 parts of multiple animal nutritional components, 20-30 parts of multiple plant nutritional components, 5-15 parts of special oil and fat components, 5-15 parts of multiple algae powder, 0.2-5 parts of multiple functional components, 0.3-3 parts of special vitamins, 0.3-3 parts of special trace elements, 1-5 parts of egg yolk powder, 0.1-1 part of lysine, 0.1-1 part of tryptophan, 0.2-2 parts of cystine, 0.1-1 part of rose essential oil, 0.1-1 part of grape polypheols and 0.1-1 part of soybean lecithin. The preparation method comprises the following steps: (1) manufacturing raw materials; (2) synthesizing a biological material; (3) converting to a cooked material; (4) puffing and granulating; (5) drying; (6) spraying and coating; and (7) performing vacuum drying. The formula feed disclosed by the invention can meet the requirements of the female minks after littering for nutrients, promote the physical restoration of the female minks, improve the conversion rate of the feed and the color and quality of hair and reduce the cost of the feed in the cultivation process.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed, in particular to a maintenance period compound feed for female mink and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, mink fur has been favored and sought after by more and more consumers as a raw material for high-grade fur. The breeding of mink is also rapidly rising in my country, but the cost of mink breeding is high, and the acquisition of a complete mink fur is accompanied by the slaughter of an adult mink. Therefore, for the breeding of female mink, special attention is paid to the recovery after giving birth, so as to ensure that the ovaries can rest and prepare for the production in the coming year. Since the female mink's sexual organs in the maintenance period are in a state of atrophy, it is necessary to add high-quality protein and other beneficial nutrients in the feed to promote the rec...

Problems solved by technology

[0003] However, in the current mink breeding process, the feed that the female mink can obtain after production is still only some ordinary livestock and poultry meat and grains, which cannot meet the nutritional needs of the female mink during the maintenance period, which often leads to pregnancy and Decreased littering ability and even premature senility have greatly affected the reproduction of mink
